Abstract
In this study we will present few novel simultaneous wireless information and power transfer (SWIPT) schemes that can be effectively used in various 5G wireless network implementations. First we will observe possibility of integration of the distributed energy beamforming principle with a cooperative communication system consisting of multiple relay users (CRUs) and multiple destination users (DUs), and exploit the performances of such system scheme. Further we propose enhanced version of SWIPT scheme, energy efficient modulation based non-orthogonal multiple access (M-NOMA) SWIPT scheme, and observe its system efficiency in terms of more harvested energy. Finally, we will propose employment of energy harvesting SWIPT scheme along with performing estimation of channel conditions by using superimposed pilot and information signal. For such scheme we will compute the optimum transmit power ratio between the pilot and information signals under varying SNR conditions and improve the accuracy of decoding process at the reception.
